[ ] Extract GPS information from exif metadata in scanner and store it in the attributes (Composite:GPSPosition tag)
[ ] Add a "location" button to the UI that launches a model popover with a map and pin on it
[ ] Make configurable in the scanner for privacy. This can't be restricted in the frontend because the information would be served regardless (it would be in the same file as the album data).
